摘要：	Shipping of materials between different locations requires methods for confirming that the correct quantities and materials are shipped and received intact. The quickest method for confirming the correct quantity of material is to weigh the material on a balance. In order for the shipper's and receiver's balances to agree, the balances must use a traceable method of periodic calibration. Once calibrated, the balances must be rechecked periodically with accepted standards to confirm that the balances remain within the allowable tolerances. This letter affirms that the balances used for weighing 3013 containers and 9975 shipping packages are staying within allowable accepted tolerances and that there is no discernable ''drift'' in the weighings that might indicate future trouble with the balance.
